Specification of Letters Patent.

Application tiled June 10, 1912. serial No. 702,716.

To (47/ w/loi/t it may concern:

lle it ltnown that l, ln'rnn Keenan, a citizen ot the United States, residing at the city o'l' (lhicago, in the county o't Cool; and State ot lllinois, have invented a new and uset'ul l mprm'ement in tias-l 'ressure Regulators, of which the following is a spccitimition.

lvly invention relates to devices tor regulating the flow and pressure o'l? illuminating gas bclnveen the service pipes and the point at which it is consumed. .tt is well. known that the pressure in such pipes varies from time to time, depending on the initial. pressure at the gas holder and the dra'tts on the volume o'l gas in the pipes at the points et consumption. This causes the nature ot a llame to vary greatly while the most etl'eotive and economical service is had by obtaining a steady, uniform pressln'e at the burners.

It is the object of my invention to produce this result, thereby providing a clear, white flame, which will be steady and brilliant and tree from noise or whistling caused by gas passing through apertures under PICSSIIIC.

l Vhile I show my invention as applied to multiple lamps in which a plurality of incandescent mantles are grouped in one illuminating device, my invention also equally applicable to any style or size of l'nirner or burners or to any kind of mechanical contrivanee using gas either for heat or light.

The principles of my invention are illustrated in the drawings, in which Figure it shows a vertical section oit' my improved device with illuminating mantles attached; Fig. 2 represents an alternative form of the same.

Further describing my invention with retcrence to the drawings, in which like characters of reference denote like parts through out: 1 represents a service pipe or service pipe connection, to which is attached an outer casing 2 having the walls 2 and the base 3. As illustrated in the drawings a head 4t having dependent mantles may be attached directly to said base. 'Within the said casing is a valve chamber having the walls 6 terminating in a closed end 7, having a central opening 8. The said walls are oft-set to term an annular seat 9 which acts as a stop and location point for the transverse partition 10. The latter has a centrally disposed opening 't'l extended upwardly by means ol" the tube 12. The partition and said tube preterably should be integrally Formed, and the said partition is 'l'urthcr provided with a plm'ality oit small openings 13. A screen or :toraminmis plate tlis' introduced into the upper part oil. the valve chamber, and into the space between it and the head ot said chamber is placed a layer ot tine steel shavings 15. An inverted cup-shaped valve ilti, having a central perl'oral ion adapted to receive the tube 12,1noves readily up and down between partition 10 and the plate it. The lower edges of said valve are adapted to set over andv inclose the openings 13 in the partition Ill. The upper portion, o't said valve is flat and adapted when in contact with plate 11 1: to close or partially close the openings therein. The valve chamber is closed by a member 1.7 and a pipe or pipes 18 connected externally to the service pipe lead thereinto and empty into the gas chamber 19. I preter to use a plurality of connecting pipes or ducts 18, thereby giving a :t'ull. and tree connection with the source oil gas supply. In many cases, however, the construction shown in Fig. 2 may be used, in which one pipe 18 is substituted for the others, such construction is cheaper and in many cases is considered sutlicient.

it will be seen that the flow of gas under varying pressures is introduced into the gas chamber Ill. A certain portion ot it passes through. the duct It and an additional portion passes through the openings "13, thereby litting the valve lit, and permitting the required tlow ot gas. As the pressure increases, however, the valve is raised. so that the top comes in contact with the plate t-t, thereby shutting oll a portion of the gas plate and permitting the "alve to drop toward or on the partition '10. lt will in etl'cct. tloat on the gas current, closing the openings above and below to control the amount o't gas which passes through the opening tl into the casing and thence through the opening 20 to the point oi consumption.

The layer o't tine steel slmvings interposed between the valve outlet and the burner eliminates the buzzing, singing or whistling sound, and at the same time making the gas [low evenly through the burner, ellcetually preventing the tliclcering or wavering light usual to ordinary burners without auton'iat-ie regulators. And when the heat generated in the burner warms the steel shavings, they in turn heat the gas flowing through the regulator, thereby expanding it and causing it to make a whiter and more brilliant light.

I claim:

1. In a gas pressure regulator; a casing, a valve chest inclosed in the casing and adapted to discharge thereinto, a transverse partition in the valve chest forming a gas chamber at the end remote from the discharge having a plurality of perforations and a central duct, a foraminous plate or screen spaced from said partition, a valve slidable on said duct and adapted alternatively to engage with said partition and said plate, and means for conducting a flow of gas from a service pipe into said gas chamber.

2. In a gas pressure regulator; a casing, a valve chest inclosed in the casing and adapted to discharge thereinto, a transverse partition in the valve chest forming a gas chamber at the end remote from the discharge having a plurality of perforations and a central duct, a foraminous plate or screen spaced from said partition, a cupshaped valve slidable on said duct and adapted alternatively to engage with said partition and said plate, and means for conducting a How of gas from a service pipe into said gas chamber.

3. In a gas pressure regulator; a casing, a valve chest inclosed in the casing and adapted to discharge thereinto, a transverse partition in the valve chest forming a gas chamber at the end remote from the discharge having a plurality of perforations and a central duct, a packing of steel shavings between said plate or screen and the discharge end, a valve slidable on said duct and adapted alternatively to engage with said partition and said plate, and means for conducting a flow of gas from a service pipe into said gas chamber.

i. In a gas pressure regulator; a valve chest, a transverse perforated partition provided with a central duct and placed in the valve chest to form a gas chamber at the inlet end, a foraminous plate or screen spaced from said partition, and a valve slidable on said duct and adapted alternatively to en gage with said partition and said plate.

In witness whereof, I have hereunto setv my hand this fifth day of June A. D. 1912,

in the presence of two subscribing witnesses.
